PHP SQL Server Couldn't connect

问题:

I want to ask you about how to connect to MSSQL Server 2005 using PHP?

I got error like this :

Connection could not be established. Array ( [0] => Array ( [0] => IMSSP [SQLSTATE] => IMSSP [1] => -49 [code] => -49 [2] => This extension requires the Microsoft SQL Server 2012 Native Client. Access the following URL to download the Microsoft SQL Server 2012 Native Client ODBC driver for x86: http://go.microsoft.com/fwlink/?LinkId=163712 [message] => This extension requires the Microsoft SQL Server 2012 Native Client. Access the following URL to download the Microsoft SQL Server 2012 Native Client ODBC driver for x86: http://go.microsoft.com/fwlink/?LinkId=163712 ) [1] => Array ( [0] => IM002 [SQLSTATE] => IM002 [1] => 0 [code] => 0 [2] => [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified [message] => [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified ) )

and here is my PHP code :

<?php
    $serverName = "192.168.183.249\MSSQLSERVER, 1542"; //serverName\instanceName, portNumber default is 1433)
    $connectionInfo = array( "Database"=>"SEI_AproCS", "UID"=>"sa", "PWD"=>"");
    $conn = sqlsrv_connect( $serverName, $connectionInfo);
    if( $conn ) {
     echo "Connection established.<br />";
    }else{
     echo "Connection could not be established.<br />";
     die( print_r( sqlsrv_errors(), true));
    }
?>

Please help to advice.

THanks

To connect with sql server you need to add dll file for sql server in the directory

wamp\bin\php\php5.3.0\ext

回答3:

Try PDO:

//$pdo = new PDO("sqlsrv:Server=$hostname;Database=$dbname;", $username, $password);  // works with proper driver for PHP.
$pdo = new PDO("odbc:Driver={SQL Server};Server=$hostname;Database=$dbname;", $username, $password);  // works with proper driver for ODBC and PHP ODBC.

I could not get the first line to work due to weird compiler version incompatibilities, but the second one worked fine after installing Microsoft ODBC Driver 11 for SQL Server

PHP Version 5.3.0 has built-in ODBC support, according to php.ini, but that still lists an active extension=php_pdo_odbc.dll here.
